- Untrack and delete compiled binaries (tarsum, gosoft.exe, rust uniq/uniq2);
ignore build outputs (dist/, bin/, *.exe, *.test, .ruff_cache/)
- Merge tools/go/ and projects/go-tools/go/ into projects/go-tools/<name>/
- Fix goipgrep .gitignore: bare 'ipgrep' pattern was ignoring cmd/ipgrep/,
so the main entrypoint was never tracked; now anchored to /ipgrep
- Archive duplicate implementations to archive/experimental/{rust,go}/
(uniq, between, tarsum rewrites); canonical versions stay in tools/
- Update README tool catalog to match new layout

# ipgrep
|
|
|
|
Extract IP addresses (and MAC addresses) from text, with optional reachability checks, reverse DNS, and ipinfo.io lookups.
|
|
|
|
## Build
|
|
|
|
```sh
|
|
./scripts/build.sh
|
|
./dist/ipgrep --help
|
|
```
|
|
|
|
## Install (local)
|
|
|
|
```sh
|
|
./scripts/build.sh
|
|
sudo install -m 0755 ./dist/ipgrep /usr/local/bin/ipgrep
|
|
```
|
|
|
|
## Usage
|
|
|
|
```sh
|
|
# Extract IPv4 addresses from stdin
|
|
cat file.txt | ipgrep
|
|
|
|
# Extract and uniq/sort
|
|
ipgrep -u -s file.txt
|
|
|
|
# Extract MAC addresses
|
|
ipgrep -m file.txt
|
|
|
|
# Reachability filter (auto chooses ICMP if permitted, otherwise TCP probe)
|
|
ipgrep -p file.txt
|
|
|
|
# Reverse DNS (IP only)
|
|
ipgrep -r file.txt
|
|
|
|
# Lookup ipinfo.io and output CSV (default header included)
|
|
ipgrep -l --format=csv file.txt
|
|
```
|
|
|
|
## Notes
|
|
|
|
- `-p/--pingable`:
|
|
- `--ping-mode=auto` (default) uses ICMP echo when raw sockets are available, otherwise falls back to a TCP connect probe.
|
|
- ICMP echo typically requires root or `cap_net_raw` on Linux:
|
|
- `sudo setcap cap_net_raw+ep /path/to/ipgrep`
|
|
- `-l/--lookup` cache:
|
|
- defaults to the OS cache dir (override with `--cache-path`)
|
|
- control size and freshness with `--cache-max-entries` and `--cache-ttl`
|
|
- MAC `-r/--resolve` and MAC `-p/--pingable` are best-effort and rely on the local neighbor/ARP table:
|
|
- Linux: `/proc/net/arp`
|
|
- Other OSes: currently unsupported without external tooling
